MATLAB: How to display an error when user enters some integer data which is an invalid data using matlab GUI

guide

hi,

there is table which conatins around 9 parameters in the following format:ParName ParVal lowerlimit upperlimit

user can edit these values when doing so, if ParVal<lowerlimt or ParVal>upperlimt then an error has to be displayed

can anyone help regarding this?

pls its very urgent

Assuming you know how to get ParVal and know what the lower/upper limits are:

if ParVal < lowerlimt || ParVal > upperlimt
  errordlg(sprintf('The parameter must be between %f and %f', lowerlimit, upperlimit));
end

Instead of clearing val after the loop, initialize it before the loop

val = [];

If you want to operate on arrays you could do it like this:

x = 1:10;
minVal = 2;
maxVal = 6;
x(x(x<=maxVal)>=minVal)
disp('Values within specified range.')
